Silver Passport — Custodial Bullion Exchange

Held in custody · attested on-chain

Buy and sell real bullion without storing it. A verified seller holds, insures, and ships the metal until redemption — your passport is the redeemable claim. Only verified sellers can mint, priced live against silver and gold spot, with a 1% royalty on every resale.

How the custody loop works

01 · VERIFY

Sellers prove EIN / W-9; the operator approves them on-chain. Unverified wallets can't mint.

02 · INTAKE

A verified seller takes the metal into custody and mints its passport — the photo locks onto Walrus.

03 · ATTEST

The metal is held and insured; the AI auditor re-attests the whole reserve back to Walrus.

04 · TRADE

Buyers move between crypto and metal; every resale pays a 1% royalty on-chain.

05 · REDEEM

Burn the passport and the seller ships the physical metal — the claim is extinguished on delivery.
